The automated control system of roller tables for strip mills optimizes the continuity of rolled goods conveying through multi-faceted collaborative operations.
In steel rolling production, roller tables for strip mills undertake the key task of conveying rolled goods, and their conveying continuity directly affects production efficiency and product quality. The application of automated control systems provides strong support for ensuring the stable conveying of rolled goods, and solves problems such as interruptions and jams in the traditional conveying process through advanced technical means and intelligent algorithms.
The automated control system collects information such as the position, speed, and weight of rolled goods in real time through sensors installed at various key positions of roller tables for strip mills, such as photoelectric sensors and pressure sensors. These sensors can quickly and accurately capture the dynamic data of rolled goods and transmit the information to the central processor of the control system. For example, photoelectric sensors can accurately detect whether rolled goods enter or leave a certain section of roller conveyor. Once an abnormal signal occurs, the system can respond quickly to avoid conveying interruptions caused by misjudgment of the position of rolled goods.
Based on the collected signals, the automated control system uses preset logical algorithms and control programs to intelligently control the operation of roller tables for strip mills. When the rolled piece is conveyed on the roller table, the system will automatically adjust the running speed of each section of the roller table according to the specifications, materials and production process requirements of the rolled piece to ensure smooth and continuous conveying of the rolled piece. For example, before the rolled piece enters the finishing mill, the system will coordinate the roller table acceleration so that the rolled piece enters the mill at an appropriate speed; after the rolled piece leaves the mill, the roller table speed can be adjusted in time to avoid accumulation or disconnection of the rolled piece. Through this intelligent speed coordination control, the pauses and collisions during the conveying process of the rolled piece are effectively reduced, and the continuity of the conveying is guaranteed.
Roller tables for strip mills do not operate independently, but work closely with many equipment such as rolling mills, flying shears, and straightening machines. The automation control system realizes real-time data interaction and command transmission with these equipment through the industrial communication network to ensure collaborative operation between various equipment. When the rolling mill completes the rolling of the rolled piece, the control system will promptly send instructions to the roller to enable it to quickly and accurately transport the rolled piece to the next process equipment; at the same time, it will work in conjunction with the flying shear to accurately control the operation of the roller according to the length requirements of the rolled piece, ensure the accuracy of the shearing timing, and avoid transportation delays or interruptions caused by improper coordination between equipment.
In order to prevent the interruption of rolled piece transportation due to equipment failure, the automatic control system has a powerful fault diagnosis function. The system will continuously monitor the operating status of equipment such as the roller motor, transmission device, and sensor. Once abnormal data or fault signals are detected, the fault point can be quickly located and the cause of the fault can be analyzed. For example, when the motor current increases abnormally, the system can determine that there may be an overload or jam, immediately trigger an alarm, and automatically take shutdown protection measures, and notify maintenance personnel to handle it. In addition, the system can also perform predictive maintenance based on historical fault data, discover potential fault hazards in advance, and perform maintenance before the fault occurs, minimizing the impact of the fault on the continuity of rolled piece transportation.
Different steel rolling production processes and rolled piece types have different requirements for roller conveying. The automatic control system can automatically adjust the control parameters and operation mode according to the changes in the production process and the characteristics of the rolled product to achieve adaptive adjustment. For example, when producing plates of different thicknesses, the system will adjust the lifting height and tilt angle of the roller according to the thickness of the plate to ensure smooth transportation of the rolled product; when switching rolled products of different materials, the speed and acceleration of the roller can also be adjusted accordingly to avoid transportation problems caused by mismatching process parameters. Through this adaptive adjustment function, roller tables for strip mills can maintain good transportation continuity under various production conditions.
The automatic control system of roller tables for strip mills comprehensively optimizes the continuity of rolled product transportation through precise signal acquisition, intelligent logic control, efficient equipment linkage, timely fault diagnosis and flexible adaptive adjustment. The comprehensive application of these technical means not only improves the efficiency and stability of steel rolling production, but also reduces the cost and risk of manual intervention, laying a solid foundation for steel enterprises to achieve efficient and intelligent production.
